  • the routing server 111 can impose a maximal time-period for each new routing rule so that the routing application should renew the routing rule before this time-period has elapsed.
  • the maximal time-period can be requested by the routing application of each device through the routing API service 114 of the routing server 111 (e.g. via a GET request).
  • the routing application can renew the routing rule automatically (in the background) before expiration of the defined time-period.
  • a new routing rule can also automatically replace an old one when the match header is the same in order to avoid deleting a routing rule before sending a new one.

Similarly, on the reverse path, another rule can be created for steering packets coming from the selected gateway function towards the corresponding device/network apparatus.
  • the routing server 111 can make use of linux netfilters based tool, such as iproute2 (ip rules, ip route), iptables and connection tracking features to enforce the policy and the routing rules at the switch 113 .
  • the routing server 111 can be already configured with a set of netfilter rules to ensure firewalling and basic routing policies at startup.
  • the routing server 111 can create a new set of specific ip rule and ip tables, mark packets coming from the device/network apparatus so that incoming packets matches the ip rule and within the ip rule creates an ip route towards the selected gateway.
  • ipset is an advanced netfilter tool able to set a timeout value on each ip rule and update the rule with a new timeout.
  • the routing server can convert high level routing application rules to a set of consistent netfilters rules to populate the forwarding table of the switch 113 .
  • the switch can be an Openflow switch configured to receive, from the routing server, Openflow rules (switching rules) according to an Openflow protocol in order to enforce them.
  • Routing server 111 can check the overall rules consistency before enforcing the new rule. For instance, if a previous routing rule exists, the routing server 111 can update the routing rule by removing the previous one. In addition, the enforced routing rules should be well written and should be removed when the device 120 or network apparatus 130 is not connected to the LAN 100 anymore.
  • the routing application 122 , 133 can ping the gateway function to check the connectivity and, without any response, can automatically send a “Remove&Update” API request to the routing server 111 through the routing API service 114 to set a new routing rule using the default gateway function (e.g. the gateway function of the CPE 110 ). The user of the corresponding device/network apparatus can be informed of this change of routing rule via the management interface 400 .
  • one of the devices 120 and network apparatuses 130 can be considered as a master device, the other devices/network apparatuses being slave devices.
  • the master device can be configured to receive routing rules from the slave devices and to send command to the CPE 110 to enforce its own routing rules and the received routing rules from the slave devices.
  • the master device can be able to amend routing rules defined by slave devices and to inform them of such amendments.
  • FIG. 5 is a flow chart depiction illustrating an embodiment where a method 500 for defining routing rules, at device 120 or a network apparatus 130 , is provided.
  • a routing application 122 , 133 stored in the device 120 or network apparatus 130 can be launched, either manually upon user's action or automatically when the device/apparatus is powered on.
  • the routing application 122 , 133 can subscribe to the publication of capacities information operated by the gateway applications 115 and 134 of the CPE 110 and network apparatuses 130 . Such a subscription allows the device/apparatus to receive capabilities information of gateway functions of the LAN 100 .
  • a user can define routing rules for routing data packets associated with the considered device/apparatus, based on the capacities information received.
  • the routing rules can be automatically defined as previously described.
  • a preferred order list of gateway functions can also be built by the user, said order list being further processed by the routing application 122 , 133 .
  • the routing application 122 , 133 can send one or several commands to the routing API service 114 of the CPE 110 . Then, the commands can be executed by the routing API service 114 of the CPE 110 to enforce the routing rules defined at 503 .
  • modules can correspond to functional modules, which may or may not correspond to distinguishable physical units.
  • a plurality of such modules may be associated in a unique component or circuit, or correspond to software functionalities.
  • a module may potentially be composed of separate physical entities or software functionalities.
  • each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s).
  • the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, or blocks may be executed in an alternative order, depending upon the functionality involved.
